. 113 BEARING FOR CRUSHING AND PULVERIZING MACHINES.

Patented Mar. 28, 1916.

Application filed May 31, 1913. Serial No. 770,833.

:atent No. 1,085,867, dated Feb. and No. 1,090,216, dated Mar. in which the lower extremity of y shaft is journaled in a rotatable bearing-said shaft carrying a trrmcated conical crusher head positioned in oppositely inclined concave crusher chamber, from the lower portion of which the crushed and pulverized "material escapes above the gear of chamber. once, -sidc from the protection of the latter chamber from dust by suitable means, by the dust guard shown and described herein by i'va-y of example and claimed in my concurrent application Serial llo; 790,785, filed Sept. 19th, 1913, which is a subdivision of the present application, an important factor is the effectual and continrous lubrication of the eccentric bearing,

lure of lubrication of the running 1on1 any cause is a serious danger in machines of this class, resulting in excessive wear. and even the melting of the Babbitt metal, and frequently necessitating a sluu';--down of the whole apparatus and costly repairs thcretc--diszulvantages and dangers which I obviate largely by providing for a continuous and positive cirrulatioir of lubricating oil between opposed bearing surfaces liorcinaftm' more fully set forth.

In the apparatus illustrated in the drawings the general arrangement and operation of the parts is substantially the same as in others .of this type, consisting essentially of a truncated conical crushing head a, rigidly secured to the shaft A, and gyrated thereby in an oppositely inclined concave crushing chamber 5, from the lower portion of which the reduced material drops into the chute chamber 0, in the usual manner. The lower portion of the gyratory shaft A, is journaled in the eccentric bearing (Z, seated in the rotatable sleeve 6, to which the driving gear 6 is secured-said driving gear a, being rotated by the pinion '72, on the power shaft P, as indicated in Fig. 1. The sleeve 0, is formed with an annular flange by which it is rotatably supported on the lower casing or bottom plate g-a floating ring 7', being interposed between said annular flange 6 and the actual rest spcctivcly to the sleeve flange 0 and to thebearing seatg (see Fig. 4). The floating anti-friction ring 7", is centralized and held in position by equidistant abutlnents 9 01 the lower casing gn and surrounding the seat g, is an annulhr gutter g, to receive the oil which issues from between the floating ring 7, .and the wearing rings c 9 The bottom of this annular gutter is inclined as indicated by dotted line in Fig. 1 to conduct the oil thus received into a pocket y, from which the oil is returned through a duct to the space in the casing below the shaft, bearing and sleeve, to again percolate upward by capillary attraction between the opposed surfaces to be lubricated,
